Strength Analysis and Calculation of JJ225/42-KC Type Oil Rig Derrick
Oil rig derrick is a large and complex metal frame with lots of bars and complex force.Moreover, the use of working condition is complex and harsh, so it is quite necessary to analyze strength and calculate oil rig derrick.In this paper, with the basic structure and force characteristic of JJ225/42-KC type oil derrick, the ANSYS finite element software is used to establish JJ225/42-KC type oil derrick structure finite element model.The strength and stability analysis of the maximum hook load working condition, the working wind load working condition and the maximum wind load working condition of three combined working conditions indicates that the overall structural design of JJ225/42-KC type oil derrick is reasonable with good both dynamic and static characteristics and the derrick meets the requirements of the strength.What is more, the derrick has a excellent overall stability.In the end, the strength of the lifting devices and the derrick leg pin of JJ225/42-KC type oil derrick are calculated and checked, showing that all meet the requirements of the strength.
